The song No News has a brief reference to the Dead in the last verse which is as follows;

She missed her bus, missed her plane; surely this can be explained
Lost her car at the mall; got locked in a bathroom stall
Playing guitar with The Band; on the road with Pearl Jam
Buried with The Grateful Dead; ca as a Parrot Head
Got derailed, got de-iced; offered as a sacrifice
FBI, CIA; if they've seen her they ain't saying
No news
Still no news!
